Example prompt: Can you estimate the age of this LinkedIn profile? Here's the profile URL: https://www.linkedin.com/in/johndoe — I need to know their approximate age or age range.

## When to prefer this

Use this endpoint when you need to estimate the age of a professional based on their LinkedIn profile data, particularly for demographic enrichment, lead qualification, or audience segmentation workflows. Prefer this over manual calculation when you have a LinkedIn URL or profile data and need a quick age inference.

## Known failure modes

- Invalid or inaccessible LinkedIn profile URL returns an error
- Insufficient profile data to estimate age returns low confidence or null result
- Rate limiting or payment failure returns 402 error
- Malformed request body returns 400 bad request
